How it works

The Ventchoke is an innovative system that is used to divert, reduce, or stop airflow completely. This innovation is designed to wrap around an existing ventilation duct and ensure that the people working in certain areas of an underground mine are receiving the maximum amount of quality air, while the other, un-manned areas of the mine are not wasting fresh air when it is not required, by one person from the ground; this ease of use is very important to increase efficiency on the job.


The low pressure air (18-20 psi) fills the Ventchoke tube which applies an inward force on the ventilation ducting .The pressure in the Ventchoke constricts the vent ducting and stops airflow through the ventilation. There is also a dump value on the Ventchoke for easy deflation when required. The Ventchoke takes approximately 30 – 50 seconds to inflate and Deflate.

The Benefits

Adding Ventchokes to your mining project means that you will be able to achieve the ultimate goals for the job while looking after the team that work hard to meet them. The necessity of a working ventilation system is paramount, and having the Ventchoke on your team is just as essential.

The Innovation Idea

The Ventchoke was an innovation of Darren Gilbertson who has spent decades of his career working in underground mining in Australia and overseas. Darren was able to see the frustrations of equipment that didn’t meet the standards of the time. One of these frustrations was the pulley system, as Darren experienced firsthand the inefficiencies this type of airflow management brought to the project.


When designing the Ventchoke system, Darren’s main concerns centred around the health and safety of the workers as well as the time and money savings a new innovation could provide to companies. With a system that is quick to install, easy to use, and robust enough to work in underground conditions, Darren knew he could improve every mine with Ventchoke. This product is completely unique and with the innovation patented globally there is nothing of its kind available on the market today.
